WALLACE B. WOLFF, OF

CHICAGO, ILLINOIS, ASSIGNOR TO AMERICAN SLICING MA CHINE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF .NEW YORK.

SLICING MACHIN invention relates to a slicing machine of the type having a rotary knife. One object of my invention is to provide an improvement in carriages for use with such a slicing machine,. whereby the material to be sliced is passed across the face of the knife and into contact with the cutting edge thereof.' Another object is the provision of such a carriage in which the work engaging member proper shall be pivoted upon said carriage for adjustment to various positions. Another object is the provision of suoli a carriage which is useful for slicing small pieces of material and which may be adjusted into position for slicing larger pieces of material. Another object is the provision of such acarriage which shall at one adjustment provide a V-shaped trough to support the material to be rsliced and at another adjustment shall present an extended generally plane and horizontal supporting surface. Other objects will appear from time to time in the course of the specification and claims.

I illustrate my invention more or less diagrammatically in the accompanying drawin s, wherein-- igure l is a side elevation of my device;

Figure 2 is a plan View with parts broken away; and

Figure 3 is a section on the line 3 3 of Figure l, with the'pusher plate removed.

Like parts are indicated by like symbols throughout the specification and drawings.

Referring to the drawings A indicates any suitable base member for myslicing machine, with the ground engaging studs A1. A2 is any suitable housing member upwardly projecting therefrom with the face plate A3 associated with the forward portion thereof and arcuately cut away as at A1 to expose the portion of the periphery of the knife B. It will be understood that any means may be employed for rotating the knife and, as such means do not form part of the present invention they are not herein indicated. In order to bring the edge of the knife into the plane of the face plate and of the later described gauge plate I prefer to tilt its axis slightly from perpendicularity to the face plate A3, the edge of the face plate penetrating a depression B1 formed in the face of the knife.

C indicates any suitable gauge plate which may be adjusted for example by rotation of the knob C1 through mechanism which forms no is therefore not illustrated.

D indicates a guide track or rod mounted at its ends on the supports D1 and herein shown as overlying the secondary guide track D2.

E generally indicates a carriage slidable along the rod D and in the form herein shown, rotatable thereabout. It is provided with a downward extension E1 which engages the track D2 and thus prevents 'rotation of the carriage about the track D. E2 are yielding buffers at the opposite ends of the carriage and E3 a handle for its manual actuation. E* indicates a generally plane and' generally horizontal supporting surface at the top of said carriage.

Extending beneath the outer edge of the surface or platform E4 0r sleeve G apertured in parallelism with .thepath of movement of the carriage. G1 indicates a work support having two upwardly and outwardly extending members G2 and G1 herein shown as in fixed angular relation and preferably integral. G2 is shown as having substantially greater lateral extension than the member G3. If desired a cover plate of enamel or any other suitable material, herein shown as G4 may be superposed upon the members G2 and G3 and is herein s iown as conforming to them' in size and shape.v G5 are lu sdownwardly depending from the mem er G1 and passing through them is any suitable pivot pin or member G6, passing through the aperture on the lug G. G7 indicates any suitable stop or stops of fiber or the like for preventing actual contact of the metallic portions of the member G1 with the top of the member E4. G8 is a similar limiting and protecting stop or buffer adapted to enga e the carriage as at *G9 when the member G1 is rotated into inoperative position. G1o indicates a lock lug on the member G1 adapted to be engaged for example by the spring latch G11 when the member G1 is rotated into inoperative position, as shown in dotted lines in Figure 3.

H indicates a pusher plate having the handle H1 with the lateral extensions H2 carrying guide pins H3 which penetrate apertures H1 in the lugs H5 extending downwardly from the members G2 and G3.

It will be realized that whereas I have described and shown a practical and operpart of the present invention and y is a bearing member ative device, nevertheless many changes might be made in size, l disposition of parts without departing from the spirit of my invention. I therefore wish my description and drawings to be taken as iii a broad sense illustrative and diagrammatic rather than as limiting me to my speciiic showing.

The use and operation of my invention are as follows:

In the operation of a slicing machine of the type herein shown it is frequently desirable to slice small objects, such as sausage, small pieces of meat and the like. It isY a convenience, in handling such objects, to prevent their lateral movement along the carriage. Ivtherefore provide the work engaging member Gl which, when in the position shown in Figure l, serves as a trough in which the work may be located and in which it is held against lateral movement and is more or less compressed between the opposed sides G2 and G3. However, when the operator wishes to trim the rind frombacon or cut large pieces of meat or the like, or cut the crusts from loaves such as sandwich loaves, it is desirable to have a more cxtended work supporting space than is pi'ovided by the member G1. I therefore pivot such member G1 to the carriage to permit itto be rotated out of' operative position. When positioned 4as shown for example in Figures 2 and 3 and rotated into inoperative position as shown in dotted lines in Figure 3, it exposes` the .extended supporting surface E4 upon which 'a ham or a piece of bacon or a loaf of bread may be positioned for slicing or trimming.

I claim:

1. In a slicing machine having a rotary knife and means for driving it, a carriage and means for guiding it across the face of said knife and a Work support pivoted upon said carriage for rotation about an axis generally parallel with the path of movement of the carriage.

2. In a slicing machine having a rotary knife and means for driving it, a carriage and means for guiding it across the face of said knife and a work support pivoted upon said carriage for rotation about an axis generally parallel with the path of movement of the carriage, said carriage bef ing provided with an extended work supporting surface underlying said pivoted work support when said pivoted support is in operative position.

3. In a slicing machine having a rotary knife and means for driving it, a carriage and means for guiding it across the face of said knife and a work support pivoted upon said carriage, said carriage being provided with an extended work supporting surface underlying said pivoted work support when said pivoted support is in operative position.

shape, number and 4. In a slicing machine having a rotary knife and means for driving it, a carriage and means for guiding it across the fare of said knife, said carriage being provided with an extended generally horizontal work snpporting member, and a supplemental work support, pivoted upon said carriage, adapted when in operative posit-ion to overlie said first mentioned supporting member, and, when at another position to be substantially out of vertical alignment therewith.

5. In a slicing machine having a rotary knife and means for driving it, a carriage and means for guiding it across the face of said knife, said carriage being provided with an extended generally horizontal work supporting member, and a supplemental work support, pivoted upon said carriage, adapted when in operative position to overlie said first mentioned supporting member, and, when at another position, to be substantially out of vertical alignment therewith, and locking means adapted to hold said supplemental support in withdrawn position.

6. In a slicing machine having a rotary knife and means for driving it, a carriage and means for guiding it across the face of said knife and a work support pivoted upon said carriage for rotation about an axis generally parallel with the path of movement of said carriage, and a pusher plate mounted for movement along said work support.
